Cyclictest's SMI counter implementation is based on turbostat's
implementation. This patch syncs cyclictest's has_smi_counter()
with turbostat's check.
>From turbostat's commits:
cdc5727 tools/power turbostat: initial KBL support
ec53e59 tools/power turbostat: initial SKX support
e4085d5 tools/power turbostat: initial BXT support
[ John & Clark, I did it in the branch devel/v2.0, but we need ]
[ this in the 0.x and 1.x series as well. ]

I applied the patch to both the stable and devel branches. I slightly
modified the commit message to read.
" Cyclictest's SMI counter implementation is based on the turbostat
tool in the Linux kernel. This patch syncs cyclictest's
has_smi_counter() with turbostat's check.
